APPARATUS FOR TREATI NG vS EWAG E.

SPECIFICATION forming part of Letters Patent No. 681,579, dated August 27, 1901.

Application filed December 29, 1897. Serial No. 664,458. (No model.)

T0 all whom t may concern.-

Beitknown that LROBERTHARRISREEVES, a subject of the Queen of Great Britain, residing at Cedardale, Putney Bridge road, Putney, London,England, have invented certain new and useful Improvements in Apparatus for Treating Sewage and Noxious Gases in Sewers, (patented in Great Britain April 14, 1897, No. 9,56G,) of which the following is a specification.

My invention relates to apparatus for treating sewage and noxious gases in sewers; and it consists in the features and in the details of construction and combinations of parts which will be hereinafter more fully described and claimed.

Figure 1 is a sectional elevation of a manhole with the apparatus fitted in position. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a vertical section on the line 3 3 of Fig. 2.

For the purpose of my invention and as I show in the annexed drawings I lit, say, a couple of vessels A B in an air-shaft, manhole, or the like, C, of a sewage or foul-wa-V ter drain. The vessel A contains permanganate of potash or other agent, such as a mixture of lime and gas-tar previously mixed under pressure and consolidated to a consistency of clay or thinned down to a liquid, and the other vessel, B, an acid or acidulated liquid, (sulfuric,) which is by a sensitive tap D allowed to fall in drips into a hollow vessel E and so becomes associated with the agent from the first-named vessel A, this issuing by its own gravity into the vessel E for admixture and overflows from the spout or lip or from a series of such. The two vessels are fixed, preferably,vin a recess well up in the manhole-shaft C, as shown in Figs. 1 and 3, and the overflow of the liquid at E falls onto and splashes into a series of pots F, porous or other, and then trickles down from them. The watersupply from the ordinary service-main enters the manhole C at G, to which is connected a drop stop-valve H, and to this is connected a deep trap, the legs I I of which are jointed up and provided with a sludge-cap J for clearing the bend of sediment. The top of the leg I has a flap or drop valve K, which shuts automatically the in- PATENT OFFICE.A

stant the pressure from the water-main ceases, leaving a column of water between valves H and K. This column of water at any pressure perfectly seals the delivery-pipe G against any air entering the main. Another branch pipe L, terminating with a tap M and needle-hole nozzle or a series of such, is so arranged that the jet or jets of water by impinging against curved plates or disks N become broken up into tine spray or mist or dew-like form, which from its floating tendency acts as a cloud and commingles with the mist or'vapor thrown olf from the chemical body while the drip and during the trickling down and fallingfrom the pots, against which a portion of the water-spray acts to keep them cool, there being heat generated when the chemicals mix together. The cloud condenses the foul gases and finally is absorbed by the sewage or water in the sewer. The water-supply pipe G is continued from the branch pipe L around the sides of the manhole C and enters the Vessel A for supplying Water thereto, the said pipe being provided at its end with a cock or valve N, by means of which the supply of water for the vessel A may be controlled.

What I claim, and desire to secure by Letters Patent, is-

1. In apparatus for treating sewage and noxious gases in sewers, the combination of a vessel in which chemicals for the formation of a disinfecting compound are mixed, drippots beneath said vessel for receiving the drippings from said vessel, a water-supply pipe and spraying mechanism on the discharge end of said pipe adjacent to said drip- Y pots.

2. In apparatus for treating sewage and noxious gases in sewers, the combination of a vessel in which chemicals for the formation of a disinfecting compound are mixed, porous drip-pots beneath said vessel into which the compound from said vessel drops, a waa ter-supply pipe whose discharge end is adjacent to said drip-pots and spraying mechanism thereon.

3. In apparatus for treating sewage and noxious gases in sewers, the combination with two vessels, adapted to contain chemicals which when combined produce a disinfecting roo compound, and each provided with means whereby its contents may be slowlyA discharged, a mixing Vessel located beneath and receiving the discharge from the chemicalcontaining Vessels, porous drip-pots beneath the mixing vessel, a water-supply pipe, a spraying-nozzle on the discharge end thereof, and deiiectors in advance of said nozzle for breaking up the spray and discharging the Water inthe form of mist to the vapors given Io ot from said chemicals.

In testimony whereof I have hereunto set my hand in presence 'of two subscribing Witnesses.

ROBERT HARRIS REEVES.
